    What is the one rep max for 80 lbs × 7 reps?

    Answer

    Lifting 80 lbs for 7 reps gives an estimated one rep max of
    98.7 lbs

    A set of 7 reps at 80 lbs is

    81.1%

    of your estimated one rep max

    Note: this is an estimate, not a tested max. Rep-based formulas are closest at 2–6 reps and drift further apart as the set gets longer. Warm up and use a spotter before attempting a true single.

    How to Calculate One Rep Max

    Epley Formula: 1RM = weight × (1 + reps ÷ 30)

    The Epley formula assumes that every extra repetition you can complete corresponds to roughly 3.33% more weight on the bar. Put your set into it:

    80 × (1 + 7 ÷ 30)

    ≈

    80 × 1.2333

    ≈

    98.7 lbs
